Hi, All
I am encountering a minor difficulty getting greencard files to work with
GHC. First of all, when greencard spits out a .hs and you give it to ghc,
it complains. The problem,for example, is the following:
_casm_ ``do {double arg1;double res1;
arg1 = (double)%0;
do { res1=sin(arg1);
%r = (double)(res1);} while(0);} while(0);'' arg1
With the error being "parse error"
The '' and `` can be substituted by " and the compiler no longer
complains... Is this correct?
Ok, fine. But, when I now pass this augmented file to ghc for compilation,
it manages to say:
T2.hs:10: Variable not in scope: `_casm_'
Compilation had errors
Or, in verbose mode:
